transform array in linkedlist

[felito]

hi guys

i want to convert my code, that use an array to a linked list, the reason is that is more flexible and fast for future implementation's of my script

but i can't convert this code

	public Deck() {
		int number[] = { 2, 3, 4, 5, 6, 7, 8, 9, 10, 3, 2, 4, 11 };

		ImageIcon[] Image = { new ImageIcon("../KingGame/src/game/img/1.gif"),
				new ImageIcon("../KingGame/src/game/img/2.gif"),
				new ImageIcon("../KingGame/src/game/img/3.gif"),
//more ImageIcon
	
 };

		deckOfCards = new Card[number_cards];
		

		for (int count = 0; count < deckOfCards.length; count++) { 
			deckOfCards[count] = new Card(Rank.values()[count % 13].toString(),Suit.values()[count / 13].toString(), number[count % 13],Image[count % 52]);
		}
	}

any help please?

What can't you convert? What exactly is the problem? To place the values of an array to a List, just iterate over the values and add them to the List.

The Arrays class has a method that can convert arrays to Lists; but it can only do that if the array contains Objects (of any type), not for arrays that contain primitives (ints, doubles etc.) For an int array you have to feed all the elements of the array to a List.

i did

package card;

import java.util.Collections;
import java.util.LinkedList;

import javax.swing.ImageIcon;

public class Teste {

	private Card deckOfCards[];
	private final int number_cards = 52;
	public ImageIcon cardImage;
	public Teste() {
		int number[] = { 2, 3, 4, 5, 6, 7, 8, 9, 10, 3, 2, 4, 11 };

		ImageIcon[] Image = { new ImageIcon("../KingGame/src/game/img/1.gif"),
				new ImageIcon("../KingGame/src/game/img/2.gif"),
				new ImageIcon("../KingGame/src/game/img/3.gif"),
				new ImageIcon("../KingGame/src/game/img/4.gif"),
                                //more
				};

		setDeckOfCards(new Card[number_cards]);
		
		LinkedList<Card> deckOfCards = new LinkedList<Card>();

		for (int count = 0; count < deckOfCards.size(); count++) { 
			deckOfCards.add(new Card(Rank.values()[count % 13].toString(),Suit.values()[count / 13].toString(), number[count % 13],Image[count % 52]));
	
		}
		
		Collections.shuffle(deckOfCards);
	}

	public void setDeckOfCards(Card deckOfCards[]) {
		this.deckOfCards = deckOfCards;
	}

	public Card[] getDeckOfCards() {
		return deckOfCards;
	}

}

and

package card;


public class Final  {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub

		final Teste gr1 = new Teste();
		
		System.out.println("Contents of ll  " + gr1.getDeckOfCards());
		
	}

}

but the result is: Contents of ll: [Lcard.Card;@53ebd75b

[JosAH]

but the result is: Contents of ll: [Lcard.Card;@53ebd75b

You're trying to print an array and that's the way arrays show their String representation. Use the Arrays.toString(yourArray) method for that purpose.

JosAH i really appreciate your help, one last question

	for (int count = 0; count < deckOfCards.length; count++) { 
			deckOfCards[count] = new Card(Rank.values()[count % 13].toString(),Suit.values()[count / 13].toString(), number[count % 13],Image[count % 52]);
		}

my doubt is, how i can do the same with LinkedList, i need a cycle to create a list of cards

thanks again

Create a List<Card> and .add(new Card( ... )) every card to it ...

52 add() ????????, one by one?

is the unique alternative??, is not possible add elements to list with a cycle?

Yep, you have to add your Cards one by one to the list but of course you can do that in a loop (if that is what you mean by 'cycle'):

for (int count = 0; count < 52; count++) { 
   yourList.add(new Card( ... ));
}
